Scratch

Does anyone have some ideas for custom blocks in BYOB? I'm out of ideas. Here are the ones I have created so far:

when gf clicked
think [hello] if < (1) = (1) > for (2) seconds // That is The First Block
repeat (3) if <true> // That Block Is Actually C Shaped, Like An If Else Block
     say (do (_*_) to the numbers (1) and (4) to get an answer) // The Do Block Is The Third, It Just Didn't Work With Block Plugin.
but if not // Part Of The Repeat (3) if <true> block
     do (_*_) with inputs (1) and (3) // That One Is Broken In BYOB Can Someone Fix It?
end
say (hi) then (bye) for (2) secs // I Didn't Make The 'Say' Part, I Made The (_) then (_) block
